The man cannon looks almost the same but it will definitely be harder to snipe people as they are coming up. Atleast it'll be able to slow down the almost-instant spawn killing that happens sometimes in the map.

I'd liked Valhalla, but I really don't think it's one of the best maps. The bubbleshield/mongoose spot is just too open and not used really well. I was hoping they had made some adjustments to that area, but unfortunately not.
